When Fidel Castro started warning the world about the dangers of an impending nuclear war, I must confess that I did not take him seriously. I figured that, if you sat on your chair for four years, in your red tracksuit, drinking rum and smoking Cuban cigars all day, your brain would probably go into nuclear mode anyway. So I reckoned he was hallucinating again.
Now Professor Stephen Hawking, who has been sitting on his chair for much longer than Fidel, is not only hinting at the possibility of a nuclear war, but also warning that people should, at all costs, avoid contact with aliens.
What conclusion do I draw from all this? Sitting on your chair for too long is definitely not good for you.
